Can’t be long till first qualifying ride?
First PBP top tip.
One week before my first qualifying ride I would always replace all brake & gear cables, chain & rear sprocket. Then I would be using it to & from work for that week to get the gears set up & fine-tuned.
It would also be set up with what lights I will be using. Water bottle cages. Bags I use a rack & a rear rack bag of a suitable size that will expand & take all your clothes when its warm during the day. This way you get the feel of the bike.
The qualifying rides are when you fine tune what you are going to take for cloths I would have with me
The comfiest pair of shoes, Socks, thin longs, shorts, vest t-shirt, short sleeved top jwcc, arm warmers, Gilet, light weight long sleeved top, thin water proof (yellow in my opinion), thin skull cap, helmet & fluorescent yellow vest for night riding & if wet (this is the law in France) fingerless mitts & full gloves Autumn. One spare pair of shorts.
It may sound daft but you do not wish chafing so make sure your clothes fit well. Once sorted out I would only use these clothes for Audax or long training rides.
